Twitter is a popular social networking service with over 300 million active users monthly, in which users can post their tweets (the posts on Twitter) or retweet others’ posts. Researchers can collect tweets using available Twitter application programming interfaces (API). For example, Sinha et al. created a manually annotated dataset to identify suicidal ideation in Twitter21. Hu et al. used a rule-based approach to label users’ depression status from the Twitter22.

Semantic search powers applications such as search engines, smartphones and social intelligence tools like Sprout Social. Named entity recognition (NER) identifies and classifies named entities (words or phrases) in text data. These named entities refer to people, brands, locations, dates, quantities and other predefined categories.

Diving into the technical bits is not necessarily the only way to make progress, and for example, these simple but powerful emojis can help as well. To compare different methods to incorporate emojis into the SMSA process, we also show the accuracy across different methods with confidence intervals. First, let’s look at the emoji-compatibility of those commonBERT-based encoder models. For sentiment analysis to work effectively, there are a few essential technical points to keep in mind. One of the key areas of delivering enhanced financial services is to improve customer service.

As you might expect, this process has a high cost in terms of annotation since we discard most of the tweets. However, it has very high precision since we collected tweets from a broad range of topics and because we have precise annotations. 3 min read – Businesses with truly data-driven organizational mindsets must integrate data intelligence solutions that go beyond conventional analytics. Businesses need to have a plan in place before sending out customer satisfaction surveys. Businesses that encourage employees to use empathy with customers can increase loyalty and satisfaction.

For instance, banks can use NLP to extract valuable insights from customer feedback to improve their products and services. Similarly, investment firms can use NLP to analyze market sentiments and news articles to make informed investment decisions. Another factor contributing to the same is the lack of sophisticated tools to handle the complexities of unstructured data. Traditional data analysis tools were designed to handle structured data and are often ill-equipped to handle unstructured data.

NLP algorithms generate summaries by paraphrasing the content so it differs from the original text but contains all essential information. It involves sentence scoring, clustering, and content and sentence position analysis. The market for NLP and voice transcription technologies today is increasingly crowded with consumer services like Otter and large vendors including AWS, Google and IBM all providing services. In this section, we look at how to load and perform predictions on the trained model. These are the class id for the class labels which will be used to train the model. This is how the data looks like now, where 1,2,3,4,5 stars are our class labels.

The neural network is trained on massive amounts of bilingual data to learn how to translate effectively. During translation, the input text is first tokenized into individual words or phrases, and each token is assigned a unique identifier. The tokens are then fed into the neural network, which processes them in a series of layers to generate a probability distribution over the possible translations. The output from the network is a sequence of tokens in the target language, which are then converted back into words or phrases for the final translated text. The neural network is trained to optimize for translation accuracy, considering both the meaning and context of the input text.

Automation & Process Control

Focusing specifically on social media platforms, these tools are designed to analyze sentiment expressed in tweets, posts and comments. They help businesses better understand their social media presence and how their audience feels about their brand. An inherent limitation in translating foreign language text for sentiment analysis revolves around the potential introduction of biases or errors stemming from the translation process44.

Language transformers are also advancing language processors through self-attention. Lastly, multilingual language models use machine learning to analyze text in multiple languages. The approach of extracting emotion and polarization from text is known as Sentiment Analysis (SA). SA is one of the most important studies for analyzing a person’s feelings and views. It is the most well-known task of natural language since it is important to acquire people’s opinions, which has a variety of commercial applications. SA is a text mining technique that automatically analyzes text for the author’s sentiment using NLP techniques4.

Because different audiences use different channels, conduct social media monitoring for each channel to drill down into each audience’s sentiment. For example, your audience on Instagram might include B2C customers, while your audience on LinkedIn might be mainly your staff. These audiences are vastly different and may have different sentiments about your company. Another plausible constraint pertains to the practicality and feasibility of translating foreign language text, particularly in scenarios involving extensive text volumes or languages that present significant challenges.

Sentiment analysis, a crucial natural language processing task, involves the automated detection of emotions expressed in text, distinguishing between positive, negative, or neutral sentiments. Nonetheless, conducting sentiment analysis in foreign languages, particularly without annotated data, presents complex challenges9. While traditional approaches have relied on multilingual pre-trained models for transfer learning, limited research has explored the possibility of leveraging translation to conduct sentiment analysis in foreign languages. Most studies have focused on applying transfer learning using multilingual pre-trained models, which have not yielded significant improvements in accuracy. However, the proposed method of translating foreign language text into English and subsequently analyzing the sentiment in the translated text remains relatively unexplored. With natural language processing applications, organizations can analyze text and extract information about people, places, and events to better understand social media sentiment and customer conversations.

Our findings suggest that Google Translate is better at translating foreign languages into English. The proposed ensemble model is the most suitable option for sentiment analysis on these four languages, considering that different language-translator pairs may require different models for optimal performance. Natural language processors are extremely efficient at analyzing large datasets to understand human language as it is spoken and written. However, typical NLP models lack the ability to differentiate between useful and useless information when analyzing large text documents. Therefore, startups are applying machine learning algorithms to develop NLP models that summarize lengthy texts into a cohesive and fluent summary that contains all key points.

Stop words are words that relate to the most common words in a language and do not contribute much sense to a statement; thus, they can be removed without changing the sentence. Furthermore, stemming and lemmatization are the last NLP techniques used on the dataset. The two approaches are used to reduce a derived or inflected word to its root, base, or stem form. The distinction between stemming and lemmatization is that lemmatization assures that the root word (also known as a lemma) is part of the language. Google Cloud Natural Language API is widely used by organizations leveraging Google’s cloud infrastructure for seamless integration with other Google services.

Sentiment analysis can also extract the polarity or the amount of positivity and negativity, as well as the subject and opinion holder within the text. This approach is used to analyze various parts of text, such as a full document or a paragraph, sentence or subsentence.
